How can anyone be confident that they have 20 or fewer? Between obvious things like computers (typically two or more processors each) and smartphones, there are processors in DVRs, DVD players, MP3 players, notsosmartphones, radios, answering machines, digital picture frames, microwave ovens, clocks, thermostats, and yes probably even some toasters.

Come on folks. EVERY device in your house that has a LED or liquid crystal display has at least one microprocessor in it; probably more than one. Here are a few things to consider in your count:
cell phone(s)
wireless phone (has two; one in the base, one in the handset)
answering machine
microwave oven
DVD player
VCR (some of still have one)
CD player (and even one of these)
MP3 player
Digital clock radio
stove
dishwasher
digital thermometer
bread machine
wrist watch
GPS (we have two)
TV(s)
cable box or satellite dish

Camcorders

and, if you have an attached garage (which I assume means its part of your home), your cars have a whole bunch of microprocessors if they're not considered a "classic."
Now go back and count again.

Traditionally, a microprocessor is a "multi-programmable" device that can be loaded with general purpose software, whereas a microcontroller is, by definition, a single-purpose chip. They may possess similar capabilities w.r.t. processing power, interfaces, etc. So the distinction is the limitation as to how the device can be used. Can it run a word processor, a spreadsheet, etc., without that application being pre-loaded? So an engine controller in a car, while it can be updated, is a micro-controller. The

This is so completely wrong it's probably not worth my time to correct it, but here goes.
To put it simply a microcontroller is a microprocessor with additional on die features, usually including memory (RAM and ROM), I/O and clock generator. All microcontrollers are programmable, and many are re-programmable, but this depends on the form of memory used for the ROM (ROM, EPROM, Flash, etc.).

Our technical room alone has about a dozen of the things (server + 5 disks, router, optical switch, 2 ethernet switches, UPS), and there's another dozen-ish in the utility room and kitchen (laundry, sewing machine, heat pump, water heater, ventilation systems, 3 freezers, refrigerator, 2 microwaves, stove). The house also has various digital clocks, thermostats, and wired & wireless sensors. Then there are the actual PCs, of which we have 4 right now, each containing multiple microprocessors (CPU, GPU) and microcontrollers (network, firewire, USB), with 1 printer, 1 multi-function network printer/scanner, another ethernet switch and another 2 UPS boxes.
